Convert Ruby to C languge, would anyone want to take a look?

I saw this sample written in Ruby code, how can I simulate it in C language?

  Open3.popen3(command) do |stdin, stdout, stderr|
      @stop_stdin = stdin
      while !stdout.eof do 
        output = stdout.read(1024 * 100)
        list_pipes.each do |out|
          out.print output
        end
      end
    end
